Explanation:
We have 4 Jacks and 52 + 2 = 54 cards in the deck. So the probability of a Jack on the first draw is 4/54. The probability of the second Jack is 3/53 as one card is out. The probability of drawing both the Jacks can be found by finding the product of these two: 4/54*3/53 = 2/477.

The correct answer is E.
